Fish DNA sampler

摘要

A system is provided for collecting cellular material from fish for subsequent DNA analysis. A channel includes a sample collection zone. A fluid ejector is directed into the sample collection zone. A fluid collector is communicated with the sample collection zone. A controller is configured to coordinate ejection of a fluid jet from the fluid ejector and collection of a fluid sample by the fluid collector. The fluid jet dislodges cellular material such as scales and mucous from the fish. The fluid collector collects that cellular material in a fluid sample for subsequent DNA analysis.

主权项

1. An automated method of collecting cellular material from living fish, comprising:
(a) providing a channel through which a fish may pass; (b) impacting the fish with a jet of fluid from a fluid ejector after automatically sensing a presence of the fish in proximity to the ejector and dislodging cellular material from the fish as the fish passes through the channel; and (c) collecting the cellular material with a fluid collector;
wherein steps (b) and (c) are automatically performed in response to the automatic sensing of the presence of the fish.
